Moving to KL in April

We are a young couple expecting our first child in Jul. Work is taking us to KL in April for a couple of years. We would like to get a sense of the areas where we could potentially rent. A lot of online forums mentioned Bangsar and Mont Kiara. The latter seems expensive, which leaves us with Bangsar.

Requesting suggestions on condos/hospitals/activities, etc. in the area. We have a budget of Protected content for a Protected content furnished condo.
